http://www.f3history.co.uk/ (click on manufacturers, Alexis, etc....) I have a picture of the Chassis tag for MK 17 Chassis #1. I will post it here if I can figure out how. I think that only one works MK 17 was built. I will have to go back and check my notes. I have two Alexis Chassis' and am always interested in sharing/learning more about them. What other information are you seeking? All for the moment, Scott
